A Square alternative for grocery stores
Last reviewed 2026-08-05 · by the RetailPOS team
Square is a fine general POS and many small groceries start on it. The friction shows up around weight-based produce, mixed-tax baskets, and — most of all — a bundled processing rate that takes a big bite of thin grocery profit on every card sale. Here is how RetailPOS compares — factually.
Where a general POS strains for grocery
Sold-by-weight & scale. Produce and deli need weight-based pricing off a connected scale with PLU lookup — clunky or unsupported on a general till.
Mixed-tax baskets. A single basket mixes zero-rated staples and taxable snacks/non-food; the POS must apply the right tax class per item automatically.
Split tender. Grocery sales often split across payment types (and, in some markets, benefits programmes); the POS should handle a split cleanly.
Processing on thin margins. A bundled ~2.6% on every card sale hurts far more in low-margin grocery than in high-margin verticals.

When to stay on Square
If your shop is a small convenience store with mostly barcoded, single-tax-rate packaged goods and little or no weighed produce, Square's free tier, first-party hardware and instant setup are genuinely great and you may not miss the grocery-specific features. The case to switch is strongest once you sell by weight, run mixed-tax baskets, or your card volume makes the bundled percentage expensive.
Migrating from Square
Export your catalogue and customers from Square, import into RetailPOS, then set up PLUs, weighed items and per-item tax classes before go-live. Steps in the Square migration guide.
Frequently asked
- Does Square support sold-by-weight groceries?
- Square's weight-based selling and scale integration are limited compared with a grocery-oriented POS. RetailPOS supports PLU and sold-by-weight off a connected scale as standard.
- Why does processing matter more for a grocery?
- Grocery margins are thin, so a bundled ~2.6% card fee eats a large share of the profit on every sale. Bring-your-own processing lets you negotiate a lower rate — often the single biggest saving for a grocer.
- Can one basket mix taxed and untaxed items?
- Yes — each item carries its own tax class, so a basket can mix zero-rated staples with taxable snacks and non-food and total correctly.
